Abstract

The invention discloses a suspension type liquid compound fertilizer and a preparation method thereof, wherein the suspension type liquid compound fertilizer comprises the following components according to weight parts: 22 to 38 parts of mother liquor of suspension agent and 78 to 62 parts of nitrogenous fertilizer, phosphate, potassic fertilizer and trace elements. The mother liquor of suspensionagent consists of the following components according to weight parts: 4 to 12 parts of hydroxyethyl cellulose, 3 to 7 parts of silicon dioxide and 15 to 19 parts of water. The fertilizer has good stability and homogeneity, and can provide trace elements and fertilizer nutrients for crops simultaneously, thus leading the crops to absorb a large amount of elements and be complemented with trace elements simultaneously, leading to high nutrient utilization rate, and saving large amount of labor cost and fertilizer cost for peasants.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a large-scale and medium-trace element fertilizer applied to crops, in particular to a suspension-type liquid compound fertilizer and a preparation method thereof. Background technique [0002] With the development of modern facility agriculture, the promotion and application of pipeline fertilization technology, drip irrigation and sprinkler irrigation and fertilization technology have begun to popularize in our country, and the application of this technology must be realized by dissolving fertilizer in water, and more and more farmers are giving crops In the process of topdressing, the fertilizer is also applied after dissolving it in water. [0003] At the same time, compound fertilizers are being used more and more widely. However, due to technical limitations, most of the compound fertilizers produced by domestic manufacturers are in solid form, a...
